Kuenzanisa kuongorora kwe caustic soda uye soda ash

Yakasiyana nesoda ash (sodium carbonate, Na2CO3) kunyangwe ichidanwa kuti "alkali", asi chaizvoizvo ndeyemakemikari emunyu, uye caustic soda (sodium hydroxide, NaOH) inonyungudika chaiyo mumvura yakasimba alkali, ine corrosive yakasimba uye hygroscopic. pfuma.Soda ash uye caustic soda inonzi zvakare "maviri maindasitiri alkalis", ese ari maviri emunyu nemakemikari indasitiri.Kunyangwe iwo akasiyana zvakanyanya kubva kune mumwe nemumwe maererano nekugadzirwa kwemaitiro uye chimiro chechigadzirwa, kufanana kwavo mune zvemakemikari zvinhu kunoita kuti vatsive kune imwe nhanho mune imwe minda yakadzika, uye mutengo wavo unoratidzawo pachena kuwirirana kwakanaka.

1. Maitiro ekugadzira akasiyana

Caustic soda ndeyepakati inosvika yechlor-alkali indasitiri chain.Indasitiri yayo yekugadzira yakatsiviwa zvishoma nezvishoma ne electrolysis kubva kunzira ye caustic pakutanga, uye pakupedzisira yakashanduka kuita ionic membrane electrolysis nzira.Yakave nzira huru yekugadzirwa kwecaustic soda muChina, inodarika 99% yehuwandu, uye maitiro ekugadzira akabatana.Kugadzirwa kwesoda madota kwakakamurwa kuita ammonia alkali nzira, yakasanganiswa alkali nzira uye yemhando alkali nzira, umo ammonia alkali nzira inoverengera 49%, yakasanganiswa alkali nzira inoverengera 46% uye dzinongoitika alkali nzira inosvika 5%.Nekugadzirwa kweiyo Trona chirongwa cheYuanxing Energy gore rinouya, chikamu chetrona chichawedzerwa.Mutengo uye purofiti yemaitiro akasiyana ekugadzira soda ash anosiyana zvakanyanya, pakati peiyo mutengo wetrona wakaderera.

2. Zvigadzirwa zvakasiyana-siyana

Kune marudzi maviri ecaustic soda anowanzo pamusika: liquid soda uye solid soda.Liquid soda inogona kupatsanurwa kuita 30% mvura base, 32% mvura base, 42% mvura base, 45% mvura base uye 50% mvura base maererano nehukuru chikamu chesodium hydroxide.Mamiriro ezvinhu makuru ari 32% uye 50%.Parizvino, kubuda kwealkali yemvura kunodarika 80% yehuwandu, uye 99% caustic soda account inosvika 14%.Soda ash inotenderera pamusika yakakamurwa kuita alkali yakareruka uye inorema alkali, ese ari muchimiro chakasimba uye anosiyaniswa zvichienderana nekuwanda.Kuwanda kwehuwandu hwechiedza alkali i500-600kg/m3 uye kuwanda kwehuwandu hwealkali inorema i900-1000kg/m3.Heavy alkali accounts inosvika 50-60%, maererano nemusiyano wemutengo pakati pezviviri zvine 10% nzvimbo yekugadzirisa.

3. Nzira dzakasiyana uye nzira dzekufambisa

Mafomu akasiyana emuviri anoita caustic soda nesoda ash zvakasiyana mukufambisa modhi uye nzira.Liquid alkali transport inowanzo gadzirwa neyakajairwa kabhoni simbi tangi rori, mvura alkali concentration inopfuura 45% kana zvakakosha zvemhando zvinodiwa zvinofanirwa kugadzirwa nickel Stainless simbi tank rori, alkali inowanzo shandiswa 25kg matatu-layer epurasitiki yakarukwa bhegi kana simbi bhakiti.Kurongedza uye kuchengetwa kwesoda ash zviri nyore, uye zvinogona kuiswa mumabhegi epurasitiki akarukwa akapetwa kaviri uye mamwe.Sekemikari ine njodzi yemvura, alkali yemvura ine yakasimba yekugadzirwa kwedunhu uye nzvimbo dzekutengesa dzakanangidzirwa kuNorth neEast China, nepo kugadzirwa kwealkali kwakasimba kwakanangidzirwa kuchamhembe kwakadziva kumadokero kweChina.Nzvimbo yekugadzira soda ash yakanyanyisa, asi nzvimbo yekutengesa yakapararira.Kuenzaniswa nesoda, yekufambisa alkali yemvura inodzivirirwa, anopfuura makiromita mazana matatu mumotokari.
